“The Walking Dead” has been a major ratings success, bringing in millions to watch the survivors fend off zombies and rival groups on AMC each week. And despite the violence and scary situations, women have been tuning in, in droves.

“It might be Norman Reedus,” Steven Yeun theorized about the show’s success with ladies, when he stopped by Access Hollywood Live on Tuesday. “It’s might be Norman Reedus, Andrew Lincoln – probably those two.”

Steven, who plays the lovable Glenn (a former pizza delivery man-turned-zombie killer and apocalypse hunk, who has won the heart of Maggie Greene), also said the show resonates with people’s imaginations about dark times.

“I think the show is so great right now just ‘cause it kind of hits home with the apocalyptic feel of the world and people are like, ‘What would I be in the zombie apocalypse or any apocalypse?’ ‘Would I be a Glenn, would I be a Daryl, would I be a Rick?’ And it’s just kind of cool to have heart in all the characters,” Steven told Access Hollywood Live’s Billy Bush and Kit Hoover.

Currently, the prison gang (Rick, Glenn, Daryl, etc.) is gearing up for a war with The Governor (and his Woodbury people), but Steven had no hints at what’s about to happen.

“I can’t say,” Steven smiled, when Kit asked who was going to win. “But that’s the joy of the show… It’s not about the zombies per se, it’s scarier to be a human and it’s scarier to be effected by humans.”

While there is plenty of scary action, there’s also just plain action going on for Glenn and his girlfriend Maggie (Lauren Cohan), who recently took a break from prison watch for a little lovin’.

“They’re in love and it’s hard to keep love like that down and out,” Steven said.

“I actually broke the news to him that that scene was filmed about three months ago, and over the course of my entire life I’ve been peppering them with like random things to prepare [them]… But he left me a nice voicemail that night in Korean,” Steven said of his dad’s reaction. “But he said like, ‘You’ve grown up quite a bit.’ It was nice.”
